How big is your biggest tank with only 1 fish, and what type of fish?

I had My RD in a 90 gal by herself because she kills everything she sees. But I now have a Jar in there with her. Seperated by eggcrate until i get the 75 I am planning for her to live out her days in.
 
20g with a single female Convict who was just hatched about 20 days ago. She's going to be my out-cross female for my linebred Convicts. She'll be about their size (20 days larger, about ^^) so it'll work out fine.
 
Well technically I still have a 8" jag and a 7" oscar together in my 125g but I just put in a divider today because the jag got too aggressive and was making life for the oscar a living hell. Later this week I'm going to go to buy a 120g(4'x2'x2') for the oscar and the jag will stay in the 125g.
 
I would think that a 55 would be good for lets say a 10" fish. Ideally. but knowing me I would have 3 and about 6 catfish and about six canisters and 3 weekly W/C's. No really anser I dont think unless its no you wont keep a 10" fish in a 10 gallon but then weve all seen it.
 
My only tank is a 75g with a Flowerhorn. Trying to get another one for Discus. More than one obviously.
 
I have a 55 with 1 pickerel a 29 with 1 ornate and a 10 with 1 betta...More single fish tanks to come lol! IDK what it is but I just like the single fish tanks.

I don't have any fish in a lone tank, even my bettas are in the same tank with a divider. I do have a 20gal with nothing but Bristlenoses, one type of fish :D.
 
I have a disfunction that prevents me from keeping only one fish in a tank.

It is called cetarius thesaurus or something like that.
